This invention relates to certain new and useful improvements in signaturestitching machines of that type illustrated in the Pat ent No. 1,750,622, issuedto Elmer WL Belluche, March 18, 1930, an d refers more particularly to the delivery mechanism-thereof.

Heretofore, the'length of signatures successfully handled by a stitching machine of the characterdescribed depended upon the overall length of its delivery mechanism and as it is sometimes desirable to stitch comparatively long signatures the size of the machine was necessarily larger than that required for the conventional run of work, thus increasing the initial and operating cost.

Therefore, this invention has as an object the provision of a delivery mechanism "for signature stitching machines and the like which is so constructed that the; overall length of the delivery mechanism bears no relation to the length of signature the machine is capable of handling. V

V A further object of this invention. resides in the provisionof a delivery mechanism for signature stitching machines and the like which is of extremely compact construction and which hasits driving elements so positioned as to leave its outer end open to permit signatures to extend therebeyond.

And a-still further object of this invention resides in the provision of means for direct- .ing a signature past the end frame of the delivery mechanism. v g V 7 With the-above and other objects in view which will appearas the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as, hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed' invention may be made as come within the scope of the claims.

In the accompanying drawings, I haveillustrated one complete example of the physical embodiment ofmy invention constructed according to the best mode I have so far devised for the practical application of the principles. thereof, and in which: i

Figure 3 is a topjplan view partly in section, of the delivery-mechanism illustrating the saddle and signature guide and being taken through Figure 1 on the-plane of line Figure 4 is a perspective view of the signature guide'shown detached from themachine,and V Figure 5 is a. fragmentary sectional view taken through Figure 3 on the plane of line Referring now more particularly to the accompanying drawings, in which like numerals designate like parts throughout the several views, 5 represents the main frame or base of a signature stitching machine, one end of which communicates with a signature conveyer or other like mechanism on which signatures are collected in groups and deposited on a substantially inverted V shaped saddle 6. The collected groups of signatures are then advanced along the saddle by other conveying mechanism, not shown, and presentedto suitable stitching mechanism, not shown, mounted from an arm 7 carried by the main frame. After the groups have been stitched, the completed books are carried alongt-he saddle 6 to the delivery end 8 of the stitcher, now about tobe described, and ejected from the machine.

Inasmuch as the specific construction of the collecting, conveying and stitchingmechanisms forms no part of the present invention they have notbeen illustrated, but reference may be had to Letters Patent Nos. 1,297,322 and 1,314,503 issued Martin Christensen for detail descriptions of typical constructions. a t

Standards 9 and 10 extending upwardly from the main frame 5 mount pairsof axiallyaligned bearings 11, 12 and 13 in which the adjacent ends of the shafts 14, 1,5 and 16 are respectively journaled, the outer end Figure 1 isa view of the delivery end of ard 10 to mount a pinion gear 17 'As i1lusof shaft 14 being extendedbeyond, the stands iris trated in Figure 2, the standard is directed laterally, as at 18 to position its upper end carrying bearings 11, 12 and 13 beyond the end of the base 5 of the machine.

The shaft 14 is adapted to be oscillated for a "Pu ose t b te de crib d .by i pinion 17-Witl1-iwhich a segment 19 meshes, the segment 19 having an arm 20 by which it is adjustably fixed to a substantially fork shaped lever -member -21 pivotally impr nted on the adiaeent end of the shaft 15: {Rocking movement is imparted to the lever memher 1 y tpitmani --GQ. 1I1eitiI g rod 522, having one end connected with the lever member, as at 23, and having its-other end connected witha crank pin 2a carried by a eam 25fiXed-to again shaft -26jjournaletl in a suitable'bearing carried by'the framef fi.

I claim:

1. In a signature stitching machine or the like, a delivery mechanism including an end supporting member, a saddle along which signatures are conveyed to the delivery mech anism, and means for guiding the signatures past the end supporting member to permit them to extend therebeyond prior to being discharged from the machine by the delivery mechanism.

2. In a signature stitching machine or the like, a delivery mechanism including an end supporting member, a saddle along which signatures are conveyed to the delivery mechanism, and a guide member positioned adjacent the saddle for guiding the'signatures past the end supportlng member to permit them to extend therebeyond prior to being discharged from the machine by the delivery mechanism.

3. In a signature stitching machine or the like, a saddle member having a part disposed at an angle to the plane of its major portion and along which signatures are conveyed, and a guide member shaped to follow the contour of the saddle member and spaced 40 therefrom to provide a passage through which the signatures pass.

4. In a delivery mechanism for stitching machines and the like, means for conveying signatures to the delivery mechanism, a sup-- port for the delivery mechanism, driving means for the mechanism, said support and driving means being so located with respect to the path of the signatures during their movement to the delivery mechanism that a signature may be extended beyond the support and past the driving means.

5. In a delivery mechanism for signature stitching machines and the like, means for conveying signatures to the delivery mechanism along a predetermined path, an end member supporting the mechanism, said end member being positioned to one side of the path of the signatures to permit the extension of a signature beyond the end member whereby a signature longer than the length of the delivery mechanism may be accommodated.

6. In a signature stitching machine or the like, a delivery mechanism including an end supporting member, means for conveying signatures to the delivery mechanism, and means for guiding the signatures as they are conveyed past the end supporting member
